Steve Jobs was the visionary co-founder, and later chief executive, of Apple, makers of the Macintosh computer, the iMac, the iPod, iPad, and iPhone, and the man behind the astonishing success of the computer animation firm Pixar, makers of Toy Story and Finding Nemo. As a result, he did more to determine what films we watch, how we listen to music, and how we work and play than any other person on the planet.
